Abstract: 1,095,548. Conveyers. R. WINKLER and K. DUNNEBIER. July 4, 1966 [July 30, 1965], No. 29926/66. Heading B8A. [Also in Division B5] In a mogul machine for casting sweets made of fondant, jelly, gum or brandy beans with sugar crust into moulding cavities formed in trays of starch, stacks S1, S2, S3 of filled trays from a drying chamber are delivered to an end 1 of the machine by a roller conveyer 4 on a pallet P1, into abutment with fixed stops (6) (Fig. 3, not shown), extending over the stack height, in which position starch trays are successively vertically removed by gripper attachment of the sides thereof to a pair of roller chains 8 on which they are inverted to discharge the tray contents at F3 and then reinverted at F4 for deposition at F5 on to horizontal conveyer chains 9, provided with entraining dogs 9<SP>11</SP>, on which they are refilled with starch powder into which moulding cavities are stamped before transfer to conveyer chains 11, also provided with entraining dogs, on which casting takes place; the filled trays on conveyer chains 12, without entraining dogs, move against a stop in a position F7 where a limit switch initiates the drive of roller chains 13 which move in a vertical direction to grip the tray which is maintained in a horizontal position and deposited on a stack S4 on a pallet P2 at the outlet 2 of the machine. Each pallet or a fresh pallet is successively advanced, upon emptying of the previous stack at the machine inlet, by the pitch of a tray stack by rotation through 180 degrees of a pair of worm and wheel 20<SP>1</SP>, 20 driven double arm levers 19, one on each side of the pallet, and each of which levers 19 carries a pair of dependent rods 17 at the ends of the lever arms which engage in turn behind successive stacks which are thereby pushed forward into position; the worm and wheel drive 20<SP>1</SP>, 20 is initiated and stopped by a limit switch 16 actuated by a rod 14 pivoted and held out of position by engagement with a tray stack. The empty pallets are conveyed through the machine on a vee-belt conveyer the drive whereof is initiated and stopped by limit switches and the belts 21 whereof engage frictionally with the underside of a pallet pushed thereon by the succeeding pallet as the first stack thereof arrives at the tray unloading position. Upon completing a stack at the machine outlet 2 a limit switch initiates a drive to a pair of cranks 29 which are connected by levers 26 and links 27 to a pair of vertically extending rails 24 which push the pallet forward on a roller track 4<SP>1</SP>, 5<SP>1</SP> by the pitch of a stack; an empty pallet (P3) (Fig. 5, not shown), is brought forward by a limit switch initiated drive to the vee belts (21) when the previous pallet (P2) is positioned to receive the last stack (S6) of trays and which empty pallet (P3) lifts and moves under a hook (30) on a rod (31) pivotally mounted to each rail (24) which hooks (30) subsequently move forward with the rails (24) to draw the empty pallet (P3) into the stacking position as the filled pallet (P2) is pushed forward to engage over a vee belt conveyer 21<SP>1</SP>, the drive whereof is initiated to move the pallet (P2) on to roller tracks 4<SP>11</SP>, 5<SP>11</SP>. The vee-belt conveyers are driven by motors through free wheel clutches. Powered rollers with friction surfaces or chains with friction blocks may be employed in place of the veebelts.
